Description

  The present invention relates to passenger conveyors such as escalators and moving walkways with stepped illumination.

  In general, an inclined passenger conveyor and a horizontal passenger conveyor have a plurality of steps connected endlessly by a step chain in a main frame (also referred to as a frame) installed in a building structure. The power is transmitted from the driving device installed on the frame entrance to the drive chain, and the step is driven by transmitting the power to the step chain via the drive sprocket installed on the main frame entrance.

  Illuminations installed on such passenger conveyors include balustrade lighting, step-down lighting, foot lighting, and the like. These are intended to make it possible for passengers to get on and off safely by brightening the vicinity of the boarding / alighting part and the vicinity of the step, and making it possible to determine the meshing part and the boundary of the step.

  The above-mentioned foot lighting is arranged near the entrance of the moving handrail in the getting-on / off part, and illuminates the periphery of the place where the foot is changed from the getting-on / off floor to the step or from the step to the getting-on / off floor. In general, this illumination often has a white color tone.

  Further, the step-down illumination is arranged below the step in the boarding / alighting section so as to make it easy to understand the boundary of the step when getting on / off. Under-step lighting allows the light to be seen from the step boundary and guides the passengers to be less likely to step on the boundary between steps. In many cases, such under-step lighting has a green color tone that is continuously lit, but there are also those in which a specific effect can be obtained by changing the color tone. This type of prior art is disclosed in Patent Document 1. In this conventional technique, under-step illumination in which illuminations of different tones are arranged in the width direction of the step is provided on the back side of the step, and the step is irradiated every one or a plurality of steps according to the timing of the passing step. The color tone of light is changed to guide the passenger to a specific step, thereby reducing the congestion of the entire passenger conveyor.
